Fuzzy analytic hierarchy process model based on particle swarm optimization
基于粒子群算法的模糊层次分析模型

According to the fact that fuzzy judgment matrix consistency tested and modified difficultly, elements weight calculated tediously existing in fuzzy analytic hierarchy process, based on the definition of fuzzy judgment matrix, this paper constructed a model of fuzzy analytic hierarchy process based on particle swarm optimizationPSO-FAHP. It proposed a nonlinear constrained optimization problem including consistency modified and elements ranking alternative of fuzzy judgment matrix, solved the problem with particle swarm optimization and analyzed the rationality. Finally, it contrasted the calculation results with some numerical examples and verified the correctness of the model. PSO-FAHP model is of certain guiding significance for practical application of fuzzy analytic hierarchy process.
